scrub vdisk Description Analyzes specified vdisks to detect, report, and store information about disk defects. Vdisk-level errors reported include: hard errors, medium errors, and bad block replacements (BBRs). Disk-level errors reported include: metadata read errors, SMART events during scrub, bad blocks during scrub, and new disk defects during scrub. For RAID 3, 5, 6, and 50, scrub checks all parity blocks to find data-parity mismatches. For RAID 1 and 10, scrub compares the primary and secondary disks to find data inconsistencies. For NRAID and RAID 0, scrub checks for media errors. A scrub can last over an hour, depending on vdisk size, utility priority, and amount of I/O activity. However, a "foreground" scrub performed with this command is typically faster than a background scrub enabled with the set job-parameters command. When the scrub is complete, the number of errors found is reported with event code 207 in the event log. You can use a vdisk while it is being scrubbed. Syntax scrub vdisk vdisks Parameters vdisks Names or serial numbers of the vdisks to scrub. Example Scrub the disks in vdisk vd1: # scrub vdisk vd1 Info: Scrub started on vdisk vd1 Success: Command completed successfully.

scrub vdisk

Description

Analyzes specified vdisks to detect, report, and store information about disk defects. Vdisk-level

errors reported include: hard errors, medium errors, and bad block replacements (BBRs). Disk-level

errors reported include: metadata read errors, SMART events during scrub, bad blocks during scrub,

and new disk defects during scrub.

For RAID 3, 5, 6, and 50, scrub checks all parity blocks to find data-parity mismatches. For RAID 1

and 10, scrub compares the primary and secondary disks to find data inconsistencies. For NRAID

and RAID 0, scrub checks for media errors.

A scrub can last over an hour, depending on vdisk size, utility priority, and amount of I/O activity.

However, a “foreground” scrub performed with this command is typically faster than a background

scrub enabled with the

set job-parameters

command.

When the scrub is complete, the number of errors found is reported with event code 207 in the event

log. You can use a vdisk while it is being scrubbed.

Syntax

scrub vdisk

vdisks

Parameters

vdisks

Names or serial numbers of the vdisks to scrub.

Example

Scrub the disks in vdisk

vd1

# scrub vdisk vd1

Info: Scrub started on vdisk vd1

Success: Command completed successfully.
